Proble creating Table Type = Select in 10gR3

In a very simple example case I have a customers table that I am trying to create a Table Type of Select in the physical layer.
Using the Admin tool I create "New Physical tabe" and enter select * from customer where region = 'East'
If I "Update All Row Counts" it now shows 56 rows - which is correct
If I try and "view data" I get an error
[nQSError: 17001] Oracle Error Code: 936, messgae: ORA-00936: missing expression at OCI cal OCIStmtExecute.
[nQSError: 17010] SQL Statement preparation failed.
If I deploy the view I can go to sqlplus and select from it.
I have tried qualifying table name and selecting specific columns - I know its not a permission issue and presumably the fact that it counted rows correctly confirms it must have generated correct SQL.
I'm puzzled - what am I missing here?

This is standard behavior..Update Row Count work fine since SELECT COUNT (*) FROM (select * from customer where region = 'East') is a valid SQL, View Data doesn't work since your columns aren't named, so OBI cant select col1, col2, etc.
Hope this explains.

Creating table type

Hi,
I am new to ABAP, can any one tell me how to create Table type for a database table in se11.
Example, I created a table ZEMP in se11, now I want to create a table type for this table. How can I do this?
Thanks,
Satish

In SE11, on initial screen, select Data Type radiobutton, enter your table type name, click create, select Table Type radiobutton, enter the attributes, click save.

Physical tables - table type 'select' query

Hello,
I've been playing around with the migrateEUL tool and have noticed that all Discoverer custom folders get translated into Physical Tables with a table type of 'select' as I would expect.
What I'm not sure about is the location in which it places these objects.
With a database data source called 'Video Store Tutorial' at the top level, a Physical Schema of VIDEO5 gets created. Inside this Physical Schema are the regular tables. The 'select' tables are placed as siblings to the Physical Select folder, and not as a child object like the rest of the tables.
Can someone please comment on what is the best practice regarding locating these 'select' tables (as children of the Physical Schema or children of the Database).
If I create a new table of table type 'select' I can only do so by right clicking the Physical Schema and choosing 'New Physical Table', thereby making this new object a child of the schema. I cannot make it a child of the database directly - although I can drag the object out from within the Physical Schema and drop it on the database name, to make it so.
Cheers,
John

Hi John,
There not really an absolut truth for this. Normaly you would make 'single schema' view siblings of there physical schema and 'multi schema' views direct siblings. It doesn't influence performances if they use the same connection pool. It's just a matter of taste.

DB Link Create table as select

I ve a query which starts with create table as select ..
When I run the select part of the query, it runs in 2 sec.
But the whole query runs in 10min. It is fetching data from dblink.
I think if select can finish in 2 sec. All is left to do is create table and insert.
Why is takin so long?
Oracle DB version 9.2.0.8

When I run the select part of the query, it runs in 2 sec.Does the select finish in 2 seconds or does it start returning rows in 2 seconds?
Big difference.

Create table as select (CTAS)statement is taking very long time.

Hi All,
One of my procedure run a create table as select statement every month.
Usually it finishes in 20 mins. for 6172063 records and 1 hour in 13699067.
But this time it is taking forever even for 38076 records.
When I checked all it is doing is CPU usage. No I/O.
I did a count(*) using the query it brought results fine.
BUT CTAS keeps going on.
I'm using Oracle 10.2.0.4 .
main table temp_ip has 38076
table nhs_opcs_hier has 26769 records.
and table nhs_icd10_hier has 49551 records.
Query is as follows:
create table analytic_hes.temp_ip_hier as
select b.*, (select nvl(max(hierarchy), 0)
from ref_hd.nhs_opcs_hier a
where fiscal_year = b.hd_spell_fiscal_year
and a.code in
(primary_PROCEDURE, secondary_procedure_1, secondary_procedure_2,
secondary_procedure_3, secondary_procedure_4, secondary_procedure_5,
secondary_procedure_6, secondary_procedure_7, secondary_procedure_8,
secondary_procedure_9, secondary_procedure_10,
secondary_procedure_11, secondary_procedure_12)) as hd_procedure_hierarchy,
(select nvl(max(hierarchy), 0) from ref_hd.nhs_icd10_hier a
where fiscal_year = b.hd_spell_fiscal_year
and a.code in
(primary_diagnosis, secondary_diagnosis_1,
secondary_diagnosis_2, secondary_diagnosis_3,
secondary_diagnosis_4, secondary_diagnosis_5,
secondary_diagnosis_6, secondary_diagnosis_7,
secondary_diagnosis_8, secondary_diagnosis_9,
secondary_diagnosis_10, secondary_diagnosis_11,
secondary_diagnosis_12, secondary_diagnosis_13,
secondary_diagnosis_14)) as hd_diagnosis_hierarchy
from analytic_hes.temp_ip b
Any help would be greatly appreciated

Hello
This is a bit of a wild card I think because it's going to require 14 fill scans of the temp_ip table to unpivot the diagnosis and procedure codes, so it's lilkely this will run slower than the original. However, as this is a temporary table, I'm guessing you might have some control over its structure, or at least have the ability to sack it and try something else. If you are able to alter this table structure, you could make the query much simpler and most likely much quicker. I think you need to have a list of procedure codes for the fiscal year and a list of diagnosis codes for the fiscal year. I'm doing that through the big list of UNION ALL statements, but you may have a more efficient way to do it based on the core tables you're populating temp_ip from. Anyway, here it is (as far as I can tell this will do the same job)

How to create table type in SAP3.1i ?

Hi Friends,
Is it posible to create table type in SAP 3.1i server ?

Hi amit,
I think there were no table types in 3.1i. Still you can define a structured table, i.e.
DATA: BEGIN OF SORT_SPFLI OCCURS 100,
        CARRID   LIKE SPFLI-CARRID,
        CONNID   LIKE SPFLI-CONNID,
        CITYFROM LIKE SPFLI-CITYFROM,
        CITYTO   LIKE SPFLI-CITYTO,
        SFLIGHT LIKE SORT_SFLIGHT OCCURS 100,
      END OF SORT_SPFLI.
You can use field-symbols, but no loop assigning.
What is it you want to do?
Anyway: Have fun with good old 3.1 - I put my old docu CD in the trash recently.
Regards
Clemens

How to create table type

I have created table type like this..
type type_cname_tab is table of varchar2(20)
index by binary_integer;
i want to know that only 20 columns are added in this table type..

i want to know that only 20 columns are added in this table type.. Maybe you may change it to a VARRAY type?
Then
SQL> declare
   type type_cname_tab is varray (20) of varchar2 (20);
   cname   type_cname_tab := type_cname_tab ();
begin
   cname.extend (20);
end;
PL/SQL procedure successfully completed.
But

   type type_cname_tab is varray (20) of varchar2 (20);
   cname   type_cname_tab := type_cname_tab ();
begin
   cname.extend (21);
end;

Issue while writing a query in table type select.in the physical layer

Hi gurus,
I am actually trying to create a table using select in the physical layer..... i acutally am not aware what it is called but its when i click a table in the physical layer i have an option table type and i chose select which allows me type my query..the query is
Select
coln name(which is a lengthly list of conversion) AS column_name
From Table name.
when i view the data rom the physical layer everthing seems to be fine. but when i try to view the data in the frnt end it gives me an error maximum length is too long than 128....
i am aware of this issue the sql server allows only column of length 128..but none of my column length is greater than 128..
Could you please help me in this
Many thanks in advance

hi veeravalli ,
Thanks for the reply....actually the corresponding reports for this have already been prepared...i created a view in the backend with the same select which i wrote before and and tried calling the view from her.. i have viewed the data and all is perfect...but when i try viewing it from the front end it error saying invaild object name select * from databasename.dbo.View_name...but i have checked the view exists in the backend...
Thanks in advance....

CREATE TABLE AS SELECT PROBLEM

Dear members,
I created a table whose definition is a select query.
for ex: I created a table xx_customer as :
create table xx_customer as
select customer_name,customer_number
from xx_ar_customer
where org_id = '87'when i run the query
select count(*)
from xx_customer;The count was 120 records.
This was done as part of performance tunning.
Now few days after the table xx_customer was created few records were inserted into table xx_ar_customer for org_id = '87' .
So ideally the count should be more than 120 but its not.
when i run the same query again
select count(*)
from xx_customer;I get count as 120 Records which is wrong.
It looks like it not refreshing data. If i run the table definition query i am getting count as more than 120 but if i do a select on the table count is still 120.
Any ideas?
Thanks
Sandeep

I cant create view. I tried that before. If i use view then my query runs for a very long time and if i create a table then the run time is reduced by half :)
So if we create Table as a select statement, then will it give data at the point of time it was created? Exactly!
Will it not give latest data?Not unless the latest data happens to be the same as the data at the time it was created.
CREATE TABLE AS is kind of like putting a photograph of yourself on your web site. If you smile, that doesn't mean the picture smiles.
CREATE VIEW is kind of like hanging a video camea from your hat, and streaming the output to your web page. As soon as you smile, the picture smiles. It's more expensive than a still picture.
A compromise apprioach is a Materialized View , which is really a type of table. Like any other table, it occupies space, and is relatively fast to use. You can define a materialized view to be refreshed at regular intervals (once a day, once an hour, once a week, ...) or whenever there is a change in the base table(s).

[Solved]SIMPLE Question ON "CREATE TABLE as SELECT".

Hi there,
I was wondering how to work it out smartly and briefly.
For example, I already have a "tableA" as following.
tableA
id name
1 name1
2 name2
create table tmp as
select id, name from tableA;
It will create the tmp table successfully.
If I want to add a new column 'tel' in tmp table,
I can run as following.
create table tmp as
select id, name, 999 tel, 'aaaaaaaaa' ps from tableA;
It will add 'tel NUMBER' column and 'ps char(9)' in tableA.
If I want to add 'col varchar(50)' in tableA,
I do not want to make a string which contains 50 characters in Select command.
How can I make it work in a smart way?
Thanks.

Is there a reason that you need this to be in a single statement? You would normally be better served here with a separate CREATE TABLE and INSERT (possibly as a direct path operation).
That said, you could use the CAST operator, i.e.
SCOTT @ jcave102 Local> create table a as select cast('a' as varchar2(50)) col1 from dual;
Table created.
Elapsed: 00:00:00.48
SCOTT @ jcave102 Local> desc a;
Name Null? Type
COL1 VARCHAR2(50)

SELECT     *

WHERE     id     IN (
                 SELECT id
                 FROM    table_2
                 WHERE   excl     IS NOT NULL
;By the way, whenever you post formatted text (such as query results) on this site, type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing.
You'll get better answers quicker if people can read:ID EXCL SEQ

123456 EX 2
123456 3
123798 EX 5
985217 EX 10

Hello Oracle Gurus,
I am trying to create a table using select * from other table.
The procedure that I am following is this:-
I have a temp table whose signature is on commit delete rows.
I insert records in this table.
when I do select * from temp_table,perm_table I get some rows.
then I try to create a result_table using this
CREATE TABLE result_table
AS SELECT * FROM temp_table,perm_table;
I see the table in created but number of records in 0. Can anyone please explain where commit takes place while sequence in this query occurs.
Thanks
Edited by: user10696492 on Nov 10, 2009 8:47 AM

Create table statement is a ddl - so an implicit commit is performed before the create statement begins. The implicit commit will delete all the rows from the temp table. If it is feasible change the definition of the temp table to on commit preserve rows.
